One of the few comedies IMHO that not only stands the test of time but perhaps even improves with age; maybe because it’s a kind of snapshot of Britain during those dark early days of WWII, and all the more authentic because it was made when people could still recall how things really were then. One of my favourite themes was the relationship between Mainwaring and Wilson, ie Capt Mainwaring’s simmering jealousy of Wilson’s social connections and his having been a “proper” officer in the Great War. Loved the way soft-hearted old Sgt Wilson would say to the men “I say chaps, would you mind awfully falling-in? Thank you so much, very kind” and Mainwaring would take his glases off and rub his eyes in that despairing way. Great stuff, never tire of watching it.
